5 INSTALLATION
Allow extra cable to form several service loops along the
cable run, if possible. Band together the cable forming the
loops using stainless steel adjustable gear clamps or tie
wire. Keep the diameter of the loops as large as practically
possible. During future maintenance, replacement, or
relocation of equipment, the extra cable can be used to
service or rewire the equipment without having to replace
the cable.
Once the cables have been pulled into position, secure the
cables to the rungs of the cable tray every 2 ft (610 mm)
using stainless steel bands, stainless steel tie wire, or
adjustable gear clamps. This ensures a neat installation,
prevents movement of the cables, and is particularly
important in the case of vertical runs of cable as it
prevents the top section of cable from supporting the
weight of the entire vertical cable run.
